+Tenks
+=====
+
+Tenks is a utility that manages virtual bare metal clusters for development and
+testing purposes.
+
+Getting Started
+---------------
+
+Tenks has dependencies on Ansible roles that are hosted by Ansible Galaxy.
+Given that your virtualenv of choice is active and Ansible is installed inside
+it, Tenks' role dependencies can be installed by `ansible-galaxy install
+--role-file=requirements.yml --roles-path=ansible/roles/`.
+
+Currently, Tenks does not have a CLI or wrapper. A virtual cluster can be
+deployed by configuring the variables defined in `group_vars/*` as necessary,
+then calling `ansible-playbook -i ansible/inventory deploy.yml`.
